I have a NOS Nitrous kit coming for my viper and need a little help with set up. The kit said everything needed is there, but i think i will need a seperate fuel supply for the nitrous. I can't see it T'ing into the factory fuel lines. Also i think a good 12 volt source is required. Do i have to run a battery or can i wire it without? My sled is a Viper S and did not come with a battery. Any advise would be great before i get started.
you will need alots of cylinder and piston spare lollll
I have spare pistons and rings but no cylinders LOL.
There must be a few on here running nitrous. Anyone?
you can call me NEXT WEEK and I will explain WHATEVER you want... 312 617-0303
Im in the caribbean right now and the internet connection is dial up!!! I'll be back on SUNDAY NIGHT and we can talk on Monday!!!!
Thanks Nosboy. I'll be calling.

well nosboy, enjoy the warmth and sun right now, cause when you get back home you're going to freeze your bag off from the bitter cold that has now set in.

what nitrous kit did you get? i was told that the boss noss kit is the most user friendly and the "safest" kit for newbees.

I would also like some info as well on the nos set up, I bought a kit off TY and the only thing I need help with is hooking up the power supply. My kit is a Boondocker, it's a fog kit in to the air box. The wiring I need is to hook up the rectifier, in my older age my wiring skills as gone down the tubs. I blame it on the beer...lol...
Thanks
Thanks

Its a NOS wet system Fogger. Injects fuel and nitrous directly into the ports.

I have a nitrous express wet system on my srx
it is a full component setup with a remote high octane reservoir . 110 octane
I added a battery on left side footwell area. I installed some radioshack rectifiers off the accessory ( lights i think) line behind the left plastic cowl
this charges the battery , but does not let the battery affect the engine ignition.
the solenoids need the battery to assure they will open and not studder due to the low current output of the srx ignition ( not sure about viper)
I added a remote nos bottle pressure gage, a tank heater, and pressure solenoid that turns off the heater if overpressure ( 1100psi)
I have a volt meter to watch the battery status to see if the ignition is keeping up with the heater draw
I also have an inline fuel pump from the high octane reservoir to the fuel solenoid and a fuel pressure gage.
I think the "complete systems" can work fine, but I am an engineer and wanted to know what everything was doing.
it was worth the effort because I had a few issues in my shakedown runs
I was coming home after first trial. literally about to hit the juice one last time when I noticed the fuel pressure was zero
the fuel line had been shaved by the full clutch shiftout run I had just made.
If I had hit the button, I would have blasted just nitrous and no fuel to suppliment and would have burned down
point is. the simple systems are turn key, but you need to be aware of what it actually does and what affects what.

Thats some good information. I was wondering about a seperate fuel system for the nos. It would make things easyer i think. I'm wondering though if the stock fuel system is pumping fuel along with the seperate nos system if it would get to much fuel when on the nos? Also do you premix the high octane fuel? The bottle pressure guage and pressure sensor is a very good idea. My system comes with a bottle heater too. That would work great at maintaining the bottle pressure. I think a fuel pressure guage is a must also. I will install a battery too, i just have to figure out the best way to hook it up. This is good stuff, Thanks.
PS, have you got any pics of your system?

the nozzles have 2 jets each. ( interchangable sizes)
there is a chart for the propper jet sizes for what horswepower, given a nitrous pressure of 1000 or so and a fule pressure of 6psi or so.
so the point is that with these gages you know that you have the right nos/fuel ration for max horsepower and not burnign it down
so you wont have too much fuel , you will have the right calibrated air/fuel ratio.
more to come later, gotta get back to work

I understand that with the seperate fuel system i'll know how much its feeding the engine, and what the pressure is. What about the factory fuel system that is also feeding the carbs with fuel? Thats 2 systems feeding fuel to the engine at the same time when the nos is activated.

I'll talk to the guy I bought my 2004 MNT Viper from. Its modded up but I had him take the NOS off. I know he had an small auxillary fuel tank with C14 mounted to be used with the NOS. He never had any motor problems (burn downs/blowups) either.
I'm thinking the main concern with nos is not the amount of fuel coming from the factory fuel system, but the nitrous/fuel mixture from the injectors. This would have to be just right to prevent burn down.
EXACTLY.... W'ell talk more about it on Monday,,but ,,, you're going in the right direction.. an AUX fuel tank with a REGULATED (and adjustable) secondary fuel supply IS A MUST!!!! I'll tell you all about it in a fewdays We've the BLUES right now and tonight the WIFE is packing because we will be in San Juan LEAVING the cruise ship (carnival Destiny),,, but 2 weeks in the caribbean is ENOUGH!!!!! I ABSOLUTELY LOVE snorkeling and we went to a BUNCH of places that were,,,lets say,,,, DIFFERENT (to say the least!!!) The Dominican Republic was ,, by FAR,, the scariest,,,, but there are some REALLY PRETTY areas by SAMMY SOSA's home!!!! Talk to you on Monday!!! gary oles nosboy

I had another long post but lost it somehow
anyway. the two systems are additive. the gas/air mix is correct through carb
and the nos/fuel is incremental power needing it's own nos/fuel mix
so the separate fuel system regulated and controlled is the best way
not saying that other combined systems aren't fine too, but this system lets you dial it in.
fundamentally, NOS does not make power on its own, it is only an oxygen source for more fuel to make more power. and the nitrogen buffers ( slows down) the burn. a perfect compound for this use.
I am still chasing clutching. unfortunately you can't have a torque sensitive CVT transmission work perfect for both on and off the NOS.
for example, guys that drag race will dial in the clutching for just racing, there sleds would be doggy ( too low rpm) if they did not hit the juice
so I have it clutched right for off the NOS ( 8500 for srx) and let it spin up when on the NOS ( 9200 !! instantly).
I am told the srx ignition retards quite a bit above 8700 so this is a very safe setup
the viper ignition maintains timing advance better at higher rps and may even make more power on the NOS than my srx, not sure.
the other thing i struggle with is keeping heat into the NOS tank. I have the heater, I blocked some of the grill area in front of the tank, and I wrapped some aluminum around the botton half of the tank and tied that aluminum to the exhaust to pull some heat off them
someone needs to make a cylindrical foam cooler to slide the tank and heater into.
when it is at 900psi, it pulls good, when it is at 1200psi, it really pulls

I'll have my notepad ready for class lol. I'm looking for another primary clutch to set up for the nitrous. Its easyer to swap clutches rather than trying to find a happy medium for both. I have a buddy close by that has a lot of excperiance with nitruos setting up race cars. I told him i was installing nitrous on my sled and he got pretty exited. I'm sure i'll get some advice from him too.
